[0026] The following specifically introduces the present utility model in conjunction with the accompanying drawings and embodiments.

[0027] This embodiment is an antigen dilution assistance and temporary storage device. As shown in Figures 1-4 , it includes a box body 1 and a cover body 2 covering the top of the box body 1. A plurality of support members 3 are correspondingly arranged on the inner wall of the box body 1. A placing plate 4 is installed on the plurality of support members 3. The outer extension of the placing plate 4 is in close contact with the inner wall of the box body 1. An effective seal can also be ensured by setting a sealing member between the placing plate 4 and the box body 1. The placing plate 4 is provided with a plurality of groups of through holes 5 for inserting antigen test tubes. An isolation sleeve 6 (with heat conduction ability) for supporting the sample test tube is arranged in each through hole 5. The dilution volume value 7 corresponding to each horizontal row of through holes 5 and the dilution concentration value 8 corresponding to each vertical row of through holes 5 are engraved on the top surface of the placing plate 4. The setting of the dilution volume value 7 and the dilution concentration value 8 on the placing plate 4 can facilitate the operator to take and place the test tubes, and reduce the occurrence of operation errors easily caused by too many samples.

[0028] As shown in Figure 1 , 3 , 5, in order to avoid the problem of low detection titer caused by the change of sample activity due to temperature difference, the box body 1 below the placing plate 4 is filled with coolant, and a pipeline 9 for introducing or discharging the coolant is arranged on the box body 1. At the same time, a valve 10 is arranged on the pipeline 9, and an observation window 11 for observing the liquid level of the coolant in the box body 1 is arranged on the front end face of the box body 1.

[0029] In order to cool down the coolant to ensure that the temperature of the antigen sample before and after dilution in the test tube is maintained within a certain range, cooling components 12 are installed on both sides of the box body 1. The cooling component 12 includes a thermoelectric cooler 13. The cold end of the thermoelectric cooler 13 is provided with a cold conduction plate 14, and the hot end is provided with a heat conduction plate 15. Both the cold conduction plate 14 and the heat conduction plate 15 are metal plates with heat conduction ability; an installation plate 16 is arranged on the outer side of the heat conduction plate 15, and a fan 17 for dissipating heat from the heat conduction plate 15 is installed on the installation plate 16; a notch for the cold conduction plate 14 to be embedded and contact with the coolant is formed on the box body 1, and the installation plate 16 is fixed on the outer side of the box body 1. The thermoelectric cooler 13 is connected to the cold conduction plate 14 and the heat conduction plate 15, and the heat conduction plate 15 is connected to the installation plate 16 through silicone. Moreover, a seal is arranged between the cold conduction plate 14 and the notch to prevent the coolant from seeping into the thermoelectric cooler 13; further, an opening corresponding to the heat conduction plate 15 is formed on the installation plate 16 to improve the heat dissipation effect of the hot end of the thermoelectric cooler 13.

[0030] In order to facilitate the control of the temperature of the coolant, a controller 18 is arranged on the front end face of the box body 1, and a sensor 19 for detecting the temperature of the coolant is installed inside the box body 1. The sensor 19, the thermoelectric cooler 13, and the fan 17 are all electrically connected to the controller 18. At the same time, a storage box 20 is arranged on the rear end face of the box body 1, and a storage battery 21 is arranged inside the storage box 20. The storage battery 21 is used to supply power to the sensor 19, the thermoelectric cooler 13, the fan 17, and the controller 18. Among them, the specific circuit connection relationship and control relationship are all prior art and will not be elaborated here.

[0031] During actual operation, the storage battery 21 supplies power to the thermoelectric cooler 13, and the same temperature as the original storage temperature is set through the controller 18. The cold end of the thermoelectric cooler 13 cools down and acts on the coolant through the cold conduction plate 14 to lower its temperature. When the fan 17 rotates, it can dissipate the heat conducted to the heat conduction plate 15 at the hot end of the thermoelectric cooler 13, so as to improve the refrigeration efficiency of the cold end of the thermoelectric cooler 13. After the temperature reaches the set temperature, the operator removes the cover body 2, then takes out the test tube containing the antigen sample from the refrigerator, inserts it into the isolation sleeve 6 of the through hole 5, covers the cover body 2, and transfers it to the antigen dilution place for dilution treatment. When diluting the antigen sample, the diluted sample test tube can be inserted into the isolation sleeve 6 again according to the dilution volume value 7 and the dilution concentration value 8 on the placement plate 4.

[0032] The above is only the preferred embodiment of the utility model patent. It should be noted that for those of ordinary skill in the art, without departing from the principle of the utility model patent, several improvements and refinements can be made, and these improvements and refinements should also be regarded as the protection scope of the utility model patent.
